CATTLE-STANCHION. v

Application filed July 14, 1915.

1 0 all whom it may concern:

Be it known that I, OSCAR LARSON, a citizen of the United States,residing at Stowe, in the county of Lamoille and State of Vermont, haveinvented certain new and useful Improvements in Cattle-Stanchions, ofwhich the following is a specification.

This invention relates to improvements in cattle stanchions and itsobject is to provide means for releasing the movable stanchion barssimultaneously; means are also provided whereby one set of the movablebars may be individually released.

WVith the foregoing and other objects in view the invention consists inthe combination and arrangements of parts to be hereinafter fullydescribed in the following specification, pointed out in the claims andillustrated in the accompanying drawings which form a part of saidspecification and in which Figure 1 is a front elevation. Fig. 2 is adetail view partly in section. Fig. 3 is a plan of Fig. 2. Fig. 4.- is asection taken on line 4-4 of Fig. 1.

Like reference characters indicate -corre sponding parts throughout theseveral views.

The reference numeral 1 designates a building in which my stanchion may.be housed and the stanchion comprises essentially a sliding rod 2 thatextends through one wall of the building and is provided with handle 8;said rod being further supported in the angular bracket 4 and providedwith the stop pin 5 which prevents its withdrawal from said bracket, andwith the lug 6 to which one end of the return spring 7 is secured, theother end of said spring being secured to the building 1. Above eachstall in the building a bell-crank 8 is arranged in a bracket 9, one endof said bell-crank being secured to the pull rod 2 and the other endbeing of hollow formation to permit its engagement with one end of thebolt 10 which bolt is movably supported thereby. The bolt 10 is formedwith an angular lug 11 and between the same and the adjacent end of thebell-crank the eye bolt 12 is carried, which bolt extends through thebeam 13 and into a metal casing 14 which is secured to said beam. Thesaid casing let is partly of curved tubular formation and this portionsupports the movable retaining rods 15, 15 which extend beyond the endsof said casing 1a and that Specification of Letters Patent.

the stanchion bars 17 are terminally carried upon said rods; saidstanchion bars being pivotally connected at their lower ends. The innerends of the rod 15 are apertured as at 18 to permit their releasableengagement by the angle pieces 19, 19 terminally carried by the eye-bolt12 and said inner rod ends are engaged by the expansion springs 20, theadjacent ends of which abut the collar 21 arranged within the casing 1-1and apertured to admit the said eye-bolt 12. Thenormal position of thestanchion bars is illustrated in full lines in Fig. 1 and re leased orinoperative position in dotted lines in that figure.

To move the stanchion bars from normal to released position the operatorpulls upon the handle 3 of the pull rod causing that rod to raise thefree end of the bell-cranks in the several stalls simultaneously, thuswithdrawing the several eye-bolts together with the sets of angle pieces19, thus freeing the retaining rods 15, which are then expellel by theexpansion springs 20.

' The device may be again placed in normal position by re-inserting theretaining rods,

To release one set of stanchion bars at a time the operator manuallywithdraws one bolt 10 from engagement with one hellcrank and thenmanually raises the eye-bolt with the result previously described'as tothe pair of stanchion bars associated with the eye-bolt.

What is claimed is .1. The combination with a pull rod, of bell-cranks,bolts terminally carried by said bell-cranks, eye-bolts carried by saidfirst named bolts, tubular casings adapted to receive one end of saideye-bolts, retaining rods slidably arranged in said casings, stanchionbars terminally engaged by said retaining rods and pivotally connectedat their lower ends, releasable connection between said retaining rodsand said eye-bolts and expansion springs within said casings inengagement with said retaining rods.

2. The combination with a pull rod, of bell cranks, bolts releasablycarried by said bell cranks, eye-bolts carried by said first namedbolts, tubular casings receiving the ends of said eye-bolts, collarswithin said casings receiving the ends of said eye-bolts, retaining rodsformed With terminal apertures movabiy arranged in said tubular casings,expansion springs connecting said retaining rods and the said collars,angle pieces normally connecting said eye-bolts and the apertured endsof said retaining rods whereby they are releasably retained in adjustedrelation and stanchion bars terminally engaged by said retaining rodsand pivotally connected at their lower ends.

In testimony that the foregoing is my own I have hereto affixed mysignature in the presence of two subscribing Witnesses.
